3 Claims. 1

The present invention relates to unloading apparatus for farm wagons and is more particularly concerned with a conveyor to be attached to an ordinary wagon of the type having flared sides.

The primary object of the invention is to provide a load discharging unit which can be readily installed in a wagon of the type referred to.

Another object of the invention is to provide a device of the character referred to which is designed to be operated by power take ofi from a tractor which also hooks on to the wagon and moves it from place to place,

A further object of the invention is to provide a device of the character referred to of simpler and more compact construction than prior devices.

With the foregoing and other objects and advantages in view the invention consists of the novel construction and arrangement of parts hereinafter described and claimed.

In the accompanying drawings illustrating the invention,

Figure 1 is a side elevation of a wagon with the novel apparatus installed and connected to a power take off on a tractor.

Figure 2 is a rear elevation of the wagonshown Figure 7 is an enlarged fragmentary section on line 1-1 of Figure 4, and

Figure 8 is an enlarged fragmentary section of the lower end of the discharge tube and conveyor.

Like reference characters, as used in the description and drawings, designate the same parts of construction.

Referring to Figure 1 of the drawings, in is a farm wagon provided with flared sides II and a bottom l2 rectangular in cross-section. The tongue l3 of the wagon can be hooked on to the rear end of a tractor T. P refers to a power take off on the tractor which is employed to operate the hereinafter described apparatus for unloading the wagon.

This apparatus, in terms of its barest essentials, comprises a trough H substantially V-shape in cross-section, with front and end walls l5 and IS. The trough is designed to be seated on the wagon bottom longitudinally and. said end walls to be bolted to the front and rear walls of the wagon.

Extending longitudinally therein is a baflie plate ll, substantially V-shape inverted, and it is suitably spaced above the bottom of the trough, as shown in Figure 3, to form a hollow body. Straps I8 to the sides of the trough support the baffle.

Extending through the'trough between its bottom and the bafiie is a rotatable conveyor consisting of a shaft I9 provided integrally with an auger type or spiraled conveyor 20. The forward end of the shaft extends through a suitable bearing in the front wall l5 of the trough and is coupled to the power takeoff P by two universals 2| and a telescopic rod 22 therebetween.

The rear end of the conveyor shaft extends through a flanged sleeve 23 mounted in the rear end of the trough and through the wall of a sectional housing 24 attached to the flange of said sleeve so as to be revolvable about the axis of the conveyor shaft I9. On the end which projects through the housing, is mounted a sprocket 25. The joint between housing and sleeve, by interlocking flanges, is designed to allow swivel motion to a laterally-extending conveyor tube 26 which is mounted onthe housing and communicates therewith.- The tube is secured in the housing by removable bolts 32 so that the tube can be taken off. As the tube 26 is adapted to be swung to the right or left in a vertical plane and the hood and spout 21 can be turned to front or rear thereof the truck can discharge its load in four different directions, as desired.

The upper end of the tube is provided with a rotatable hood having a discharge opening and a downwardly directed spout 21. The. lower end of tube 26 is also closed and mounted in suitable bearings in both ends is the shaft 28 of an augertype conveyor 29, similar to conveyor 20.

- The lower end of shaft 28 extends through the end of the tube 26 and carries a bevel pinion 29 which meshes with a similar pinion mounted on a .26 can be made in various lengths to suit the needs of the work and these alternate tubes may be readily substituted.

In operation the commodity is loaded into the wagon for transportation. When it arrives at its 3 destination and unloading is desired, the conveyors are operated by the power take off of the hauling tractor. The conveyor in the wagon will feed the grain or other commodity to the elevating conveyor at the rear and through the'elevator tube to the point of discharge.

As different embodiments may be made of this inventive concept and modifications may be made in the embodiment hereinbefore shown and described, it will be understood that the matter herein is to be interpreted as illustrative merely,

. and not in a limiting sense.

What I claim is: l. The combination with a farm wagon body including a fixed flat bottom, a trough extending longitudinally of said body and supported on said bottom, a baiile plate arranged in superimposed spaced relation with respect to said trough and resting upon the walls of the latter to thereby form a hollow body, a rotatable spiraled conveyor extending through said hollow body having one end projecting beyond the front end of said wagon body for attachment to the power take- 08 of a tractor, the other end of said conveyor projecting from the rear end of said wagon body and terminating at a point contiguous to said rear end, a housing surrounding the end of said conveyor projecting from the rear end of the wagon body and mounted for rotation about the axis of said conveyor, .a laterally-extending tube communicating with said housing and secured to the latter, a second rotatable spiraled conveyor in said tube having one end overlapping said first-named conveyor, and means operatively connecting the overlapping end of the second spiraled conveyor to the adjacent end of the firstnamed conveyor.

2. The combination with a vfarm wagon body including a fiat bottom, a V-shaped trough extending longitudinally of said body and supported on said bottom, a sleeve mounted inthe rear end 01 said trough, a bafiie plate of substantially inverted V-shape arranged in superimposed spaced relation with respect to said trough and resting upon the walls of the latter to thereby formv a hollow body, a rotatable spiraled conveyor extending through said hollow body having one end projecting beyond the front end of said wagon body for attachment to the power take-oft of a tractor, the other end of said conveyor projecting through said sleeve and terminating at a point contiguous to the rear end of said wagon body. a housing surrounding the end of said conveyor projecting from the rear end of the wagon body and mounted on said sleeve for rotation about the axis of said conveyor, a laterally-extending tube communicating with said housing and secured to the latter, a second rotatable spiraled conveyor in said tube having one end overlapping said first-named conveyor, and means operatively connecting the overlapping end of the secondnamed conveyor to the adjacent end of the firstnamed conveyor.

3. The combination with a farm wagon body including a fixed flat bottom, a trough extending longitudinally of said body and supported on said bottom, a fixed baille plate arranged in superimposed spaced relation with respect to said trough and resting upon the walls of the latter to thereby form a hollow body, a rotatable spiraled conveyor extending through said hollow body and having an end projecting from the rear end of said wagon body and terminating at a. point contiguous to said rear end, a housing surrounding the projecting end of said conveyor and mounted for rotation about the axis of said conveyor, a laterally-extending tube communicating with said housing and secured to the latter, a second rotatable spiraled conveyor in said tube having an end overlapping said first-named conveyor, and means operatively connecting the overlapping end of said second-named conveyor to the projecting end of said first-named conveyor.
